## What kind of change does this PR introduce?
Docs update. Aligns documentation and style guides with the **Sign in /
Sign out / Sign up** platform standard.
Closes DOCS-1328. Related to
[#49874](https://github.com/supabase/supabase/pull/49874).
## What is the current behavior?
Docs style guides prefer _login_ / _log in_. Guide prose uses mixed
login and sign in wording.
## What is the new behavior?
- [WORD_LIST.md](apps/docs/WORD_LIST.md) and
[copywriting.mdx](apps/design-system/content/docs/copywriting.mdx)
document the sign in standard
- Design-system auth examples updated
- Guide prose and API reference spec descriptions updated
### Terminology
**Standard:** Use _sign in_, _sign out_, and _sign up_ as verbs. Use
_sign-in_, _sign-out_, and _sign-up_ as nouns and adjectives. Match
Studio UI labels (**Sign in**, **Sign out**, **Sign up**).
**Preserved intentionally:**
| Category | Keep as-is | Example |
| -------- | ---------- | ------- |
| Feature name | social login | `/social-login`, `features.mdx` heading,
OAuth provider section |
| URL slugs | `login` in paths | `/phone-login`, `/login-flows`,
`choosing-login-flow` |
| CLI | `supabase login` / `supabase logout` | Reference ids
`supabase-login` / `supabase-logout`; executable commands unchanged |
| SDK methods | `logout()` | Kotlin/Swift method names in API reference
titles and examples |
| Third-party UI | Provider product labels | Facebook Login, Kakao
Login, portal **Login** buttons |
| Postgres | Database terminology | login privileges, login credentials,
login via role |
| Audit/logging | Log prose | "Generates the following **log** in the
Postgres Logs" |
| Code and routes | Paths and filenames | `app/login/`, `Login.tsx`,
`demos/android-login` |
| External URLs | Third-party login pages | `dash.cloudflare.com/login`,
`console.neon.tech/login`, `vercel.com/login` |
| API identifiers | Event and field names | Audit actions
`login`/`logout`, `should_logout_user` |
## To test
- Run `pnpm lint:mdx` in `apps/docs`
- Spot-check `features.mdx`, `social-login.mdx`, and a provider guide
(e.g. Facebook, Kakao)

## Summary by CodeRabbit
* **New Features**
* Added an **Access Tokens** section to configure JWT expiration with
dedicated Save/Cancel controls and success/error toasts.
* Enforced a maximum JWT expiration value (must be **less than 604800
seconds**).
* **Bug Fixes**
* Updated the Sessions auth page text to better clarify configuration
for access tokens, refresh tokens, and user sessions.
* **Documentation**
* Updated JWT expiration guidance to point to **Auth settings → Access
Tokens** (replacing legacy JWT secret references).
* **Chores**
* Expanded automated tests covering Access Tokens saving and validation.
* **Refactor**
* Removed JWT expiration editing from the legacy JWT Secrets area,
consolidating it under Access Tokens.

Begin the process of moving our MDX files into their own content directory.
Fixed a few minor bugs re: ToC and tabs not rerendering consistently on page navigation. (The ToC thing wasn't a problem before the refactor, the tabs thing is a problem on prod.)
Moved MDX files can't import their own components, so everything they require needs to be back in the component prop for mdx-remote's serializer. Cleaned this up a bit and lazy-loaded heavy/rare stuff. Also, the component prop doesn't take arbitrary objects (only actual components), so imported data has to be wrapped in a component.
